Alvarado (oblique) fired a scoreless seventh inning in Triple-A Durham's win over Syracuse on Tuesday, allowing no hits and two walks while recording a strikeout.
A report Monday indicated Alvarado would take the hill Wednesday and Thursday for the Bulls, but that schedule was apparently moved up by a day. Alvarado threw 26 pitches overall Tuesday, with control problems leading to him getting only 12 of those offerings into the strike zone. Alvarado is scheduled to toe the rubber again Wednesday, after which he'll likely be evaluated for possible activation.
